Key Ingredients
A cyclic nonapeptide hormone with a disulfide bridge, synthesized in the hypothalamus. Research documents its role in social cognition, pair bonding, and neuromodulatory pathways.
Discover the researchDescription
Oxytocin is a 9-amino-acid cyclic neuropeptide hormone (Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2) produced in the hypothalamus and released by the posterior pituitary gland. It plays a central role in social bonding, reproductive physiology, and stress regulation.
Research Background
Oxytocin has been extensively studied for its role in social cognition, trust, and affiliative behavior. Research in both animal and translational human models has explored intranasal oxytocin administration and its effects on amygdala reactivity, stress response, and prosocial behavior. This product is for research use only.
